3 claims. (o1. 29g-'ssi l rIhis invention relates to improvements inportable liquid diffusing devices.

The invention has particular application' to that class of diffusor inwhich air or steam is supplied under substantial pressure through aflexible hose tof a portable nozzle.v Ordinary hand sprays operated byself-contained pumps are ineiective because the low pressure availabledoes not result in adequate diffusion. I have worked with diffusorsinstalled in more or less fixed positions on semi-portable stands andsupplied wth high pressure fluid and while these are very satisfactoryfor some purposes, they will not under all circumstances avoidprecipitation. l5 Complete diffusion seems to be promoted by a more orless constant movement of the nozzle about the area of the space whichis being treated so that no one portion of the air in such space issubjected to. a prolonged treatment. While movement of the diffusingdevice from point to point is thus a desirable incident to treatment, itis also desirable to carry a substantial quantity of the insecticidedisinfectant, deodorant, perfumes, or other liquid to be sprayed, andone of the objects of the present invention is to provide a diffusingdevice of this general character with a steady rest which greatlyfacilitates the transportation and manipulation of the diffusingmechanism and also provides a stable support which prevents thediffusing mechanism from being tipped over by the weight of the hose andmaintains it erect under all conditions.

It is another object of the invention to provide a novel and improveddiffusor head adapted to receive connection with a conventional jar and`provided with an improved disposition of the nozzles and filling cap.

In the drawing:

Figure 1 is a view in vertical axial section showing a device embodyingthe present invention.

Figure 2 is a plan view of the device.

Figure 3 is a rear elevation of the support on a reduced scale showingthe preferred form thereof.

Like parts are designated by the same reference characters throughoutthe several views.

I have shown at 3 the flexible hose through which the compressed gasused in the spraying operation is delivered. Ordinarily compressed airwill be used subject to the control of a valve 4 at the end of the hose.

The valve casing is rigidly connected with the spraying mechanismhereinafter to be described by means of a short length of rigid pipe 5which serves asa handle for the device and is preferably covered with apiece of hosev 6 which serves as a grip and heat insulator. A flat nut Iscrewed ontofthe pipe clamps to the valve casing 4 a plate 3which'preferably broadens toward its base as indicated in Figure 2 andmay conveniently be made of aluminum, for lightness. This plate servesas a steady rest as will hereinafter be explained.

The forward end of pipe 5 is screw threaded or otherwise fixed in a boss9 in the spray head It. This spray head consists of a casting internallythreaded at II to receive any standard glass or metal jar I2 in whichthe insecticide or other spray material is contained. Integral ears atI3 are apertured to receive the hooked ends of tension springs I4 whichsupport a skeletonized strap metal carrier I5 which supports the bottomof the jar, preferably through an interposed cushion I6 of sponge rubberor the like to minimize shocks when the device is set down.

The spray head II) is provided integrally with an upstanding half domeat I8 in which there is centrally disposed a screw threaded flange I9with which a conventional closure cap 20 is detachably engageable. Theopening within the flange facilitates the refilling of the jar I2without the necessity of unscrewing the jar from the spray head.

The half dome I 8 is spanned from front to rear by an integral tube 2Iwhich communicates with the interior of the boss 9 and comprises anextension of the pipe 5. Screw threaded into the end of tube 2l is anozzle tting 22 which-delivers a pneumatic jet across the end of a pipe23 which leads from a point near the bottom of jar I2 upwardly throughthe fiat wall 24 of the spray head I0 into adjustably operativeproximity to the nozzle 22.

The horizontal Wall 24 of the spray head and the adjacent vertical wall25 at the forward side of the half dome I8 provide a convenientarrangement for the disposition of the spray tube 23 and the atomizingnozzle 22, where they can be accurately located and adjustably xed withreference to each other.

The pipe 2| serves as a baffle which prevents the liquid in jar I2 frombecoming splashed through the vent 26 which is provided in the closurecap 20. Yet the pipe 2I does not sufdciently obstruct the fillingopening to reduce the ease with which the supply of liquid in the jarmay be replenished. While the jar I2 is readily removable for cleaningor for filling, the ller cap makes the removal unnecessary for thelatter purpose.

The length of the steady rest or support at 8 is substantially equal tothe combined height of the spray head l0, the jar I2 and the holder andcushion I5 and I6 so that when the device is set down on the oor or anyother flat surface, it will be maintained upright in the position shownin the drawing. The length of pipe 5 spaces the support 8 suflicientlyfar to the rear of the spraying device so that it is difficult to upsetthe mechanism notwithstanding the weight of the hose 3 attached thereto.Y.

The weight of the device and the hose is substantial and as the operatormanipulates the spray and swings it from side to side, he finds it veryconvenient to be able to rest the plate 8 against his leg or some otherportion of his body. The operator may also grasp plate 8 with one orboth hands to direct or guide the spray upward or downward. The breadthof plate 8 enables it to serve as a partial protection to the operator,tending to keep from his person some of the mist which might tend todrift backwardly along the apparatus, or any of the spray material whichmay have carelessly been allowed to accumulate on the outside of thejar.

I claim: l Y

1. A device of the character described comprising a spray head having ajar receiving thread and a half dome arising thereaboveY to providesurfaces approximately at right angles, a pipe connected with one ofsaid surfaces and extending below said thread to be received into a jar,a pressure nozzle connected with the other of said surfaces in operativeatomizing relation to the pipe, a supply tube spanning said half domeand communicating with said nozzle, together with a vented cap appliedto the top of said half dome, said dome providing a filling opening andhaving a threaded ange for the reception of said cap.

2. A device of the character described comprising the combination with areceptacle, a spray head thereon having a tube communicating with thereceptacle, and a nozzle connected with the spray head and disposed inatomizing relation to the tube, of a tubular supply pipe connected withsaid spray head and communicating with said nozzle, said pipeconstituting a handle lprojecting rigidly from the spray head, means"providing a stop at the end of the handle remote from the spray head, aplate of generally triangular form having in its apex an apertureengaged over 'the handle and abutting the stop, the base margin of saidplate being substantially at the level of the bottom of the receptacle,and means including a hose connection threaded to said handle and inclamping engagement with said plate.

3. A spray device comprising the combination with a sprayhead having anozzle and a receptacle therebeneath, of a pipe communicating with saidnozzle and rigidly connected with said spray head and projectingrearwardly therefrom to constitute a handle therefor, a hose connectionat the end of the handle remote from said spray head, a steady-restcomprising a plate having a f broad and substantially imperforateportion below said handle end and extending to a margin substantially atthe level of the bottom of the receptacle, and means including said hoseconnection for fixing the position of said plate and securing it at saidhandle end.
